AEROPLANE-MOTOR.

i Specification of Letters Patent. Patented Jan. 27, 192i).

Application. filed December 11, 1917. Serial No. 206,646.

To all whom it may concern:

Be it known that I, FRANK WOOD, a citizen of the United States, residing at Mount Comfort, in the county of Hancock and State of Indiana, have invented a new.

and useful Aeroplane-Motor, of which'the following is a specification. I

The subject of this invention is a motor; of the internal combustion engine type and intended, primarily, for an aeroplane motor.

A principal object ofthe invention is to improve the connection between the piston rods and the main shaft.

Another object is to provide a gyi'atory element to impart rotary motion to the main shaft.

Still another object is to provide a two cycle engine.

A further object is to cooling the engine.

With the foregoing and other objects in provide means for .view'which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details .of constructlon hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can'be made within the scope of what is claimed without departing from the spirit of' the invention.

A practical embodiment of the invention is shown in the wherein:

Figure 1 is a view in elevation of a-motor constructed in accordance with the invention;

Fig. 2 is a'front elevation, a portion of accompanying drawing,

.the front plate removed;

Fig. 3 is a central longitudinal section taken through a diametrlcally arranged pair of cylinders;

Fig. 4 is a fragmentarydetail showing in end elevation the connection ofthe piston rod with the gyratory member;

Fig. 5 is asection on the line 5-5 of Fig. 4.

Referring to' the drawings by numerals of reference:

In carrying out the invention there is provided a suitable cylindrical or drum-like casing 10 the central portion of the head of which is offset outwardly as at 11 and a hub 12 is provided at the center of the head of this offset portion 11. The head of the cylindrical casing 10 extends beyond the cylinplaced therein.

drical body to form a flange 13, while at the other end of the body an outwardly extending annular flange 14 is formed.

Secured to the flange 14 by machine screws 15- or otherwise, is a plate. 16 which forms a head or closure for the casing 10. The plate 16 may be reinforced by the radially extending ribs 17 which are formed on its outer face, while a centrally disposed standard 18 projects from its inner face and this standard terminates in a substantially spherical end 19, which projects into a socket 20 formed at the cent-er of a disk or plate 21. The plate. 21 is preferably circular and may be reinforced with radial ribs 22 and 23 formed on its rear and front faces, respectively. An arm 24 extends forwardly from the center of the plate or disk 21 and terminates in a spherical end 25, which is journaled in a socket 26 formed in the end of a crank 27 The end portion of the crank 27 is separable so as to form a divided socket to permit the spherical end 25 to be easily This end is bound in place by the machine screws 28 or otherwise. The crank 27 has a Weighted extension 29 for the purpose of providing a counterbalance.

\Vhile this portion has been shown and described as a crank it is to be understood that the same may be in the form of a fly wheel if desired.

The crank 27 is integral with or rigidly afiixed to the drive shaft 30 which shaft is journaled in the before mentioned hub 12.

A series of cylinders 31, herein shown as six, are spaced about the head of the casing 10 and are secured tothe head and the flanges 13 by machine screws 32 or otherwise. The cylinders are provided with the usual spaced annular ribs 33 and with spaced ribs 34 aranged on the cylinder heads for the purpose of radiating heat and cooling the cylinders. An exhaust port '35 is likewise provided in the side of each cylinder 31 and communicates with the exhaust manifold-36 which practically encircles the motor.

An inlet port 37 is provided through the flange 13 for each cylinder 31 and at these ports suitable check valves, indicated at 38,

-- are provided. Fuel is supplied to the cylend of the cylinder when the piston has reached the limit of its forward stroke.

Within each cylinder31 is a piston 41 which has a short flange or deflector plate 4-2 projecting from its head near the periphery thereof and adapted to lie in front of and spaced slightly from the head end opening Each member 43 of the piston is tapped to receive the end of a tube 45 which extends through the packing gland H and forms a housing for the piston rod #16. The piston rods 46 are of any suitable form and are pivot-ally secured to the pistons in the ordinary way, as indicated at 47.

The end of each piston rod is tapered as at 4:8" to take into a tapered aperture which extends through a block -19 and in which it is held by a nut 50. Each block 49 is provided with trunnions 51 which rockin bearings formed in the prongs of the yoke end of a pin 5:2- and end blocks 53 which are bound on the yoke ends by machine screws or otherwise. The pins 52 are spaced at suitable intervals about the disk 21 of which they extend radially, the plate being cored for their reception. The pins are bound in place by the clamping straps 53 one member of whiclris integral with a rib 23 and the other member clamped to the first member by bolts or otherwise. A collar 54 may be provided on each pin to lock the same against, longitudinal movement.

A hub 55 is secured by a key 56 or otherwise to the shaft 30 and the hub is formed with a conical flange 57 provided with spaced apertures 58. An annular plate extends from the conical flange, with which it is integral, and extending from one face of- As is evident this structure pro it is directed by the fan against and between the sides of the cylinders.

. Attaching lugs are provided at suitable points on the device for the purpose of anchoring or connecting the motor to suitable same. may be placed in an upright position if desired. This would probably be of particular advantage when the motor is driving a helicoptor,

Having thus described the invention, what is claimed, as new and sought by Letters Patent, is:

1. In a motor, a support, a plate mounted for gyration in they support, cylinders mounted on the support, pistons in the cylinders, means for connecting the plate and cylinders, a shaft journaled in the support, a fan hub keyed to the shaft, said'hub including a conical flange to providea pocket, and having spaced apertures formed therein, vanes integral with the hub and adjacent the pocket, for drawing air through the apertures and pocket, said cylinders being arranged annularly about the fan.

2. In a. motor, a support, cylinders on the support, pistons in the cylinders, a shaft journaled in the support, a fan hub keyed to the shaft, fan. blades integral with the hub, said fan hub having means disposed between the fan blades for allowing air tobe drawn therethrough by the fan blades, said cylinders being arranged annularly about thefan.

3.' In a motor, a support, cylinders on the support, pistons in the cylinders, a shaft journaled in the support, a fan hub keyed on the shaft, said hub having a pocket formed adjacent one extremity thereof, the walls of the pocket having openings formed therein, fan blades integral with the hub,

and adjacent the openings for drawing air through the openings, said pistons being arranged annularly about the cylinders.

In testimony that I claim the foregoing as myown I have hereto affixed my signature in the presence of two witnesses.

FRANK lVOOD.
